There seems to be no improvement in Bobbi Kristina Brown's condition since she was found unresponsive in a bathtub on Saturday, and investigation is currently on to find out what exactly caused the accident.

As per reports, Bobbi has since been released from North Fulton Hospital and moved to Emory University Hospital in Atlanta at her father's order. Bobby Brown has also made sure his daughter's husband, Nick Gordon, isn't anywhere near Bobbi. He suspects that Gordon "is responsible for his little girl currently in the intensive care unit," a source told Radar Online.

Gordon was also banned from Bobbi's bedside at the North Fulton Hospital on Saturday after he made an "unwelcome appearance," reported Radar Online, adding that Gordon was physically escorted out of the floor by hospital security.

Bobby's attorney, Christopher Brown of Brown & Rosen, LLC, also told the media outlet they were investigating the events that led to Bobbi's hospitalisation. Authorities have reportedly seized Gordon's phone for clues, and the Georgia townhouse where she lived with Gordon is currently off-limits to the 25-year-old.

Bobby's attorney also raised questions on the Bobbi-Gordon relationship stating that the 21-year-old was not married to Nick Gordon. This revelation comes despite the fact that Bobbi announced to the world she wed Gordon last January, and since then she has often referred to Gordon as her "incredible husband."

Bobbi and Gordon told TMZ last year that their marriage was official and noted that Bobbi's mother, the late Whitney Houston, would be happy with their union. "I would tear up, this is exactly what she wanted, us together," Bobbi said.

Bobbi's relationship with Gordon has raised eyebrows for long, as Bobbi's late mother, Whitney Houston, raised Gordon as a son. Although she did not officially adopt him, many felt it would be wrong for Bobbi and Gordon to tie the knot.

As for Bobbi's condition, the family released a statement saying she was still fighting for her life. "Bobbi Kristina is fighting for her life and is surrounded by immediate family," the statement said. "As her father already stated, we are asking you to honor our request for privacy during this difficult time." Meanwhile, Radar Online added that family members have lost hope and are discussing funeral arrangements.
